Answer: 2,200 Kcal
Explanation: An average adult requires at least 2,200 Kcal in a day for maintaining his/her weight and carrying on everyday activities. The average calorie requirement varies person to person depending on numerous factors such as person’s sex, age, height, weight, and level of physical activity. In each sex and age category, the higher limit of the range is for individuals who have active lifestyle and the lower limit of the range is for individuals who have sedentary lifestyle.
